or installing any hardware components.

2. Disconnect all ribbon/wire cables from the motherboard, including those
for the keyboard and mouse.
3. Remove all add-on cards.
4. Install one CPU (making sure it is fully seated) and connect the chassis
speaker and the power LED to the motherboard. (Check all jumper
settings as well.)
No Power
1. Make sure you have connected all three power connections: one 20-pin
(ATX PWR CONN), one 4-pin (J47) and one 8-pin connector (J38).
